DILATOR.

l Application filed December 12, 1923. .'SerialiNo. 680,248.`

The ,invention relates' to anatomical dilators and it consists in the novel features hereinafter described and claimed.v

The object of my invention is to provide a dilator of simple and eflicient form adapted to be used fory dilating parts of the anatomy, as the rectum, va gina or mouth of the womb, and fory applying liquid medicament or wash into or beyond. the dilated parts.

In the drawings, Figure 1 is a perspective view of the dilator having an intermediate portionof the container broken away. K

Figure 2 is a longitudinal sectional view i5 thereof, the dilator shown extended.

Figure 3 is a perspective view of arm'lO. n Figure 4 is a perspective View of a shaft used in'connection with this improved dilator. The dilator consists of a set of articulated .2o spreader sections 1f, arranged in the general pointed end of the container is closed by a rub- 1 bei' cap 3 which is removed when the dilator is to be used. The fiange plate v5 which is attached to the container hermetically closes 30 the large end of the container.'

The container may contain a` liquid and when the pointed end thereof is inserted, the outer portion of the container may be'collapsed by pressure, whereby the liquid is forced from the pointed end portion of the container into and upon the parts of the anatomy to which the Vdilator is applied. A nipple 6 is attached to one of the spreader sections and passes through the' side of the container and connects with a tube 7, which, in turn, connects with a liquid fountain or bag 8. A clip 9 is mounted upon the tube for interruptin the flow of liquid therethrough. n

n arm 10 is threaded unto the nipple 6 and is screwed down tight against the rubber washer 17. The arm 10 is provided with a socket 12 and a shaft 14 having a square shoulder 15 and a handle 16 and is journaled-.in said socket, said shaft being held in said 5o socket by a pin 12 which ispassed through y the socket.

A tube 18 connects with nipple 6 which extends along the reduced end portion of the spreader and out to the tip of the small end of the container. The fountain 8 may contain diate of its ends. Thus when the shaft is roa medicated liquid andwhen the dilator is applied the said liquid may flow bygravity from the-fountain bag through the tube and be de-v posited upon and beyond the parts of the anatomy which are dilated by the spreader.

An'endless cord surrounds. the container at the outer spaced end portions of the sections v 1 ofthe spreader and is connected to a pin 13 which is mounted on the shaft 14 intermecoj tatedthe cord is wound thereon whereby the outer spaced ends of the spreader are drawn toward each other and the diametrically reduced or smaller ends thereof arey spread apart. As the smaller end portions thereof are inserted in tlie parts of the anatomy tobe dilated, the part is expanded and the liquids may be applied as herein stated. The sections of the spreaders are kept in position by the ring 20 which allows the spreader sections to swing or rock as the cord is wound upon the shaft.

Having describedv my invention that which I claim to be new anddesire to procure by Letters Patent is:

1. In a device of the character described a dilator and means for spreading the same, a Y medicament container surrounding said dilator, a fluid container connected to said dilator, a tube extending from said second container to the terminal ofthe dilator, means forming a passageway extending from said first container to the terminal of the dilator, and a ring forming part of the dilator to keep the spreading means apart.

2. In a device of the character described a dilator and meansfor spreading the same, a

' medicament container surrounding said dilator,a fluid container connected to said dilator, a tube extending from said second con-` gf tainer to the terminal of the dilator, said first container having communication with the terminal of the dilator, and a ring forming part of the dilator to keep the spreading means apart, said spreading means having spread apart terminals. p

3. In a device of the character described a vdilator and means for spreading the same, a medicament container surrounding saidy dilator, a fluid container connected to said dilator, a tube extending from said second'container to the terminal of the dilator, said first container having communication with the terminal of the dilator, a ring formingA part ofV the dilator, said spreading 'means 110 having spread apart inner ends and means for drawing said inner ends together to spread the outer parts of said spreading means.

4.. In a device of the character described a dilater and means for spreading the same, a medicament container surrounding said dilator, a fluid container connected to said dila tor, a tube extending from said second container te the terminal of the dilater, said iirst container having communication with the terminal'of the dilater, 'a ring forming part of the dilatoigsaid spreading means having spread apart inner ends, and means for draw-V ing said inner ends together to spread the -said inner ends together to spread the outer imei-r4 parts of said spreading means, said means consisting of a cord encircling said container over the inner ends of said spreading means, andmeans for contracting said cord.

G. In a device of the character described a dilater and means i'or spreading `the same, a medicament container surrounding said dilator, a iiuid container connected to said dilater, a tube extending from said second container to the terminal of the dilater, said first container having communication with the vterminal of the dilater, a ring forming part en r`lilater, said spreading means having spread apart inner ends and tightening means :tor drawing said inner ends of said spreading means together to spread the outer parts et said spreading means. Y

7. A dilater having a pair'of spaced apart swingable sections, a flexible encasement mounted over the rear pbrtions of said sections, means co-operable with the rear portions ef said sections for forcing said rear portions inwardly, a container formed rearwardly ci' said encasement, and a second container having means extending through said encasenient for discharging fluid therefrom to a peint adjacent the forward end of said sections inwardly thereof.

In testimony whereof I aix my signature.
